Create or modify a Richfaces Listener

akrima Jun 2, 2014 10:42 AM

Hi,

I have an XHTML page with two tables A and B. In the first table, there are some inputText fields. Changes of their value should be automatically reflected in the other cells and the other table.

My current solution using beans performs badly because the calculations are made at the level of beans. Is there a way to perform it in the presentation level, bypassing the beans or not, as the principle of Excel fomula?

It's possible de adapt our own Richafaces Listener?

I am not sure what you mean by "Richfaces Listener" but you can use javascript to work with data on the client side. If you use a4j:ajax then instead of @actionListener you'd use @oncomplete to call a javascript function. Although even sending data to the beans shouldn't perform horribly, unless the table is big.

Yeah , the table is big that's why it takes more time to load when i modifiy it , i can use "spreadsheet" like zkoss framwork whitch use the formula like Excel so all calculate methode are execut juste on prestation and not on model (beans) as my case.
Can you tell me please if i can modify Richfaces Listener or create a listener ?

I'm not sure what you mean by that. What do you want to do with the listener? What do you need to happen?

As I said, you can use javascript to achieve something similar. I just don't understand what do you want to do with a listener when you don't want to send data on the server.
